CCTi 2200 Watt Electric Demolition Jack Hammer 1400 BPM Concrete Breaker, includes Point and Flat Chisels (Model: CDH65A)

Bought for digging out rock to level ground for slab. Texas has so much rock just under the surface. Worked perfect. Cheaper than renting and thought I’d just sell it to recoup some $ after the project. Surprisingly, I’m keeping this as it has proved very useful for other small projects.

I bought this one as a back up to this one "XtremepowerUS 61103 Jack Hammer w/Point & Chisel Bits Electric 2200W Demolition Construction Concrete Breaker Punch Drill" as the XtremepowerUS one was said to have more power but also had a high rate of arriving in broken unusable condition and I really could not afford any additional delays in completing my backyard work. XtremepowerUS says it is 55 foot pounds of impact which is about 75 joules. This one says it is 33 foot pounds of impact force or 45 joules. I could not tell any difference between the 2 units. This unit is slightly harder to handle though, as the unit will seize with the tool extended past the impact point. I think that is more a problem with quality control than any appreciable difference in the brands, just as likely the defect could have been with XtremepowerUS. I honestly am 100% convinced they come from the same molds and built in the same factory. Everything was identical right down to the power cord ties.Anyways, this one comes better packaged, with all the same items and the color is a bit less drab than the XtremepowerUS one which came with a broken case. For the price, it is perfect for home improvement activities.I used this to drive tee posts into the pockets of retaining wall blocks to positively lock them to the ground and prevent shifting over time. My ground is a hard clay and the large powerful contractors had reached their limit driving the posts into the ground with a normal hand driven post driver. It took me less than an hour last night and an hour today to drive 88 posts into the hard ground until only between 7 and 15 inches were still above ground. It was a mixture of 6 foot and 5 foot posts, 6 foot posts I left 15 inches out of the ground (2 retaining wall blocks) and the 5 foot posts 7 inches (1 retaining wall block).I'll return this item due to the more difficulty in handling from the XtremepowerUS one, shame really, this one looks better.

It works well, and a bargain price. The instructions can barely be called that, as no effort was put into translating into English on how to assemble and insert the chisel ends. Easy enough to figure out. The handle must be removed to replace it in the carrying case, and that is a pain.

I've used this far more than I ever expected to. Bought for 1 job. Have done at least 15 in the few months I've owned it. Works great with one minor exception. The lower handle comes loose. I just changed out one of the nuts to Teflon coated and hasn't been a problem since.The gloves and mask that come with it are a joke. Probably made for a 6 year old child. Definitely not an adult

My only complaint is having to buy and add oil. Broke up concrete for me no problem for my small basement project, probably not a lifetime tool, which cost 4x this. Included accessories are useless landfill.

This jackhammer is powerful, it made quick work of an 8 inch thick concrete wall. For the price this is one hell of a tool. The only criticism I may have is the side handle is kind of cheaply made, but for under $200 you can't beat this hammer

When it works properly it does a fantastic job. The downside:1. The mechanism that’s supposed to hold the chisel in the tool mostly doesn’t work. The chisel works itself out of the tool on almost every cut. Very frustrating! I keep stopping to retrieve the chisel (sometimes it’s stuck) and reinstall it. Very time consuming.2. Sometimes, but not real often, the motor spins but the chisel doesn’t engage. When it does this I check the oil level but it’s always fine.3. The ‘manual’ that comes with it sucks! Especially the part where it tells how to put the oil in. When I open the oil gauge there’s a felt piece that sticks up. It’s shown in the parts view but the manual never tells why it’s there or what its purpose is. There’s also nothing telling you how much oil to add. It only says to fill it to the level shown in the picture but the only way to do that is to remove the oil gauge, put in some oil, reinstall the oil gauge and check the level. If it doesn’t have enough, or too much, remove the gauge again to add or remove oil, reinstall the gauge and check it again.
